Woon-HEEL-TURNING MACHINE vTo all w/'Lom t may concern:

.Be it known-that I, LELAND B. WHIPPLE, a citizen of the United States,residin at Rochester, in the county of Monroe and tate of New York, haveinvented certain Improvenients in W ood-Heel-Turning Machines,/of whichthe following description,`

in connection with the accompanying drawings, is a specification, likereference Vch'aracters on the drawings indicating like" parts in theseveral figures.,

.This invention relates tomachines for- *vor from the breast to the rearof the blank, does' not permit cutting about the blank continuously fromone breast corner to the other. Any attempt to cut against the grain ofthe wood is. attended by unsatisfactory results due to the gougingv ortearin;l effect of the .cutter upon the wood fibres, consequently twooperations are necessary, one in the direction of the grain of the woodon one side of the blank, and the other in the direction of the grain ofthe wood on the opposite side of the blank. Owing to -the surfacecontour of the finished heels which extends along the' sides and aboutthe rear of the heels, it is expedient to cut the blanks from the breastcorners on each side in the direction of the grain ofthe Wood, to themedial line of the heel at the rear by means of cutters molded or formedto 4produce the desired surface. the present invention,therefore,.consist s of a novel organization of heel blank carrier onwhich the heels blanks are mounted and rotary molded cutters mounted toact upon the heel blanks at opposite sides of the feedl ing path astheyare presented by the carrier.

The cut or finished sides and rear surfaces of wooden heels may, in someinstances, be conveniently formed by a simple traversing movement ofmolded cutters shaped to produce the desired contour, but heel stylesvary. Some require a greater fullne'ssor bulge towards and at the rearAn important feature of speieauqn of Lettersratent. Patented Apr, 18,1922, Application'led August 4, 1919. Serial No.

of the heel leading to the heel seat.while others necessitate greater orless fullness toward .the tread surface at the rear of the heels, whilea difference in contour at the breast and at the rear is frequentlydemanded.

Another important feature ofthe invention,=therefore, consists inmounting the molded cutters for tilting movement at each side of thefeeding path of the heel blank carrier and automatically effecting achange 1n the angular position of the cutters as they act progressivelyalong a blank. In some cases the tilting movement of the cutters may besufficient, but a further feature of the invention consists inadditionally supporting the cutters for movement heightwise of the heelblanks as theyy are tilted relatively thereto. l ters are thus broughtinto action at different Aparts of the heel, and, a variation in shapelis thusproduced.

In carrying this feature of the invention into practical effectthe/tilting movement of the cutters in the present instance of theinvention is produced about an axis passing transversely of the cutters,and means are provided for changing at will the relation of the cuttersand tilting axes longitudinally of the cutters, thus adapting 'thecutter actionto a variety of different heel styles.

Since the molding cutters are mounted to act upon the blank fromlopposite sides of the feeding path of the blanks, means are provided tomove the cutters laterally about the rear of the blank. Unless the cutsmade by the respective cutters accurately meet at the rear of the heel,a rid' e or uncutpor Different parts of the cut- Y heel or slightlybeyond this point as the heel blank being treated is moved inthedirection of feed by the carrier.

When the cutters movelaterally inwardA to finish the rear of a heelblank, they must be returned to outer or initial position to 45 andcarrying clamps for securing blanks side portions they act in thedlrection of the grain of the wood and good results may be secured bytraversing the blanks and cutters relatively at 'high speed, but as thecutters move. inward about the rear of the heel should .the same s ed of'relative traverse be maintained, t e cutters would' travel over agreater length of `surface in a u nitof time, thanwhile workingalong theside of theheel. This would tend to produce unsatisfactory results,especially in view of the fact that'as the cutters move inward at therear of the heel they cut, to some extent, crosswise of thegrain.

.Another important feature of the invention, therefore, consists inrelatively traversing the cutters and blanks at convenientlyl variablespeed as the cutters move around the blanks to secure the most eflicientcutting action.

A still furtherv important feature of the invention consists inautomatically tilting the cutters, and moving them in -a vertical andhorizontal. direction as they operate upon a blank. These movements ofthe cutters are preferably secured by pattern means which, in thepresent instance, are movable with the heel blank carrier.

Economy of operation and increased output depend to a large extent `uponthe facility with which the` heel blanks may be secured to the carrierand the finished heels discharged therefrom. The carrier inI its broadsense may be variously contrived but a good practical form of carrierconsists of a series of links flexibly connected together thereto. Afurther feature of the present invention, therefore, consists of `acarrier having blank holding clamps and means for automatically clampinga presented blank, moving it past the molding cutters,

and automaticallydischarging the finished heel.

Various other features of thel invention and novel combinations of partstwill' be hereinafter described in addition to those above referred toand in connection 'with the accompanying drawings which illustrate onegood practical form of the inven-vtion, it vbeing-understood that inits-true scope the invention may embrace various forms and modificationsIn the drawings:

The main frame of the machine may be of suitable construction forsupporting the some of the Variations formed ill the p operating parts,Vand as shown, comprises f the -side members 1 suitably connected by theties 2. Mounted in the machine frame is the shaftl 3 which may be drivenfrom -any suitable source of power. In the present instance of theinvention the shaft 3 is 7 of a clutch referably splined to the motorshaft shat 6 for rotative movement therewith buty permissive movementlongitudinally thereon. Mounted in the machine frame in `axilal ali mentwith the motor .shaft 6 is the sha t 8 carrying the-other member l9 ofthe clutch and providedfwith a worm 10' which engages the worm .wheel 11mounted on the shaft 3, substantially. as I shown in Fig. 7.

Pivotally mounted at 12, Fig. 10, upon a bracket 13 projecting from themachine frame, is the yoke 14, Figs. 2 and 10, carrying pins or rolls 15which engage a circumferential groove in the hub portion 16 of theclutch member 7, thev construction being .such that upon rockingmovement of the motor shaft 6 and the intermediate shaft 8.

Secured to the pivot shaft 12 which carries the yoke 14 is an arm 17,Figs. 2 and 10, to which is connected the rod 18. The other end of therod 18 is jointed to an arm 19 secured tothe shaft 20, Figs. 2 and-10,which preferably extends transversely of the machine frame and isprovided at a convenient point with an operating handle 21,

the construction being such that upon movement of the handle 2l by themachine attendant, the clutch members 7 and 9 may be engaged ordisengaged at will.

The shaft 3 has secured thereto the two similar crank arm's 22, Figs. 1and 7, and as these crank arms are of similar construction, descriptionof one will suffice for both. The crank arm 22 has a hub portion whichserves to connect the crank arm with the shaft 3. Extendinglongitudinally of the crank arm4 is a guide-way 23 in which is mountedthe slide 24,- Fig. 10. The slide 24 is adjusted lengthwise theguide-way 23 by suitable means, such, for instance, as the adjustingscrew 25, which, in the present instance, is shown as threaded into theslide 24 and has a collared head portion at 26 which engages at oppositesides of the slotted lug 27 projecting from the crank arm 22, theconstruction being such that upon manipulation of the adjusting screw25, the slide 24 may be moved towards or from the axis of rotation ofthe shaft 3. j

The crank arms 22, as indicated in Fig. 7, are preferablyarranged 18()oapart, that is,

the slides 24 are supported diametricallyatopposite .sides of theshaft3`for a purpose that will more fully appear.

Pivotally connected to each of the slides 24 at 28 is a' link 29, theopposite end of each of which is connected at 30, to arms 31.,

respectively, mounted to rock upon the supporting shaft 32. Each of thearms 31 has an opposite member 33`carrying a feed pawl 34 pivotallyconnected to its arm at the upper portion 35 and normally under thevcontrol of yielding means for causing the respective pawls to engagewith the heel blank carrier, to be hereinafter described, and permitdisengagement of the pawls therefrom. In the present instance, each ofthe pawls 34 is provided with a rod 36 pivotally connected tothe pawl at37 and extending loosely through a lug 38 carried by the pawl actuatingmember. Between the lug 38 and a collar 39 carried by the rod 36, is thespring 40, the construction being such molded cutters to act fromopposite 'sides of the path of relative traverse movement and uponopposite sides of the blanks..

In' the present instance ofthe vinvention the carrier for the'heelblanks comprises a series of links 42 and 43 pivotally connected attheir end portions at 44 into a flexible endless chain construction. Thecarrier A thusformed of the flexibly connected members 42 and 43,passesabout suitable rotary supporting members 44 and45 mounted for rotativemovement upon' the machine frame substantially as indicated in Fig. 1.The rotary supporting members 44 and 45 have fiat peripheral portions,as indicated in Fig. 1, for properly conforming to the links 42, 43, asthe supporting members 44 and 45 rotate. The supporting members44 and 45may be appropriately carried in suitable bearings 46, 47, in the machineframe and in order that the carrier A passing about the supporting'members 44 and 45 may be properly adjusted to conform the upper .run ofthe carrier A to its proposed path of movement, the bearings 46, 47 maybe adjustablyl mounted' in'the yokes 48, Fig. 1, and adjusting screws50maybe provided for adjusting the bearings 46 and 47.

The pawls 34, heretofore described, cons titute one convenientform offeeding means for the heel blank carrier- A, and are adapted to engagewith lugs or in recesses 51, bestshown in Fig. .10, as the pawlssuccessively move in their operating stroke. The recesses 51 are formedin the under surface of the link membersof the carrier, andthe feedpawls, under the .action of the springs 40, arehenabled toengageanddisengage the recesses 51 to feed the `carrier on the loperating strokeof the pawls. Inasmuch as the feed pawls 34 are actuated from the crankarms 22 arranged 180o apart, as hereinbefore described, vit follows thateach of the feed pawls will give to the carrier` A a relatively. slowstart and finish to its feeding movement, and a relatively high rate oftravel between the start and finish. In other words, the carrier A ismoved at varying speeds, the purpose of which will more fullyhereinafter appear.`

The heel blank carrier A has mounted thereon a series of clamps forsecuring the Wooden heel blanks in-xed position relative to the carrieras it moves or feeds the from an arm 52, Figs. 4 and 7 and 10, the Uoverhanging upper end portion of which is provided with a springactuated clamping member 53 which may be provided with a suitableroughened or toothed engaging surface to securely hold one end of theblank. 'As indicated in Fig. 4, the clamping member 53 is mounted on apin 54 having the adjustable head portion 55 preferably formed byadjustable nuts, and mounted in the recess of the overhang of the arm 52and surrounding the pin 54, is a spring 56, the normal tendency of whichis to depress or project the clamping member 53.l

Mounted for-sliding movement relative to the link 43 of the carrieristhe lower clamping member 57 to the upper end portion of which issecured a clamping block 5S conveniently securedto the clamping member57 by suitable means, such as the screw 59. The clamping member 57 .eX-tends through the link 43 and'at its lower end portion has rotativelymounted thereon the roller v60 adapted to engagea trackway 61 mounted onthe machine frame below the carrier. The clamping member 57 has guidingconnection with the link l43 by means of the winged portions 61X on they a lug 66 carried by the machine-frame andl .clamping member 57 whichembrace a guide in position to be engaged bythe rolls 604 as the carrieris given its feeding movement, and in order that the trackway 61 may beproperly positionedfor effecting the clamping action desired between theclamping Amembers 53 and 57, hereinbefore described,

the trackway is adjustably supported at each end-upon the machine frame,as indicated in Fig. l. The adjustment of the trackway 6l may bevariously effected, but in the present instance of the invention, anadjusting screw 65, Fig. 1, passes through engages the trackway 61. Suchadjusting device may be provided at desired intervals along thetrackway, or atv either end, as circumstances may'dictate, theconstruction being such. that the trackway may be 'properly adjusted tosecure the desired clamping action of the heel blanks between the upperand lower clamping members.

It. is sometimes desirable to support the lower run of the carrier-as itpasses in its idle position between' the vrotary supports 44 and 45, asindicated in Fig. 1. flo this end a supporting bar or track 67 isadjustably secured to the machine frame below the track 61 and inposition to be engaged by the side portions of the carrier A, asindicated in Fig. 2, as the carrier moves in its idle position betweenthe rotating supporting members 44 and 45. The adjustabilityv of thesupports 67 may be secured by means similar to' those descrlbed for thetrackway 61, as indicated in Figs. 1 and 2.

ln the'present instance of the invention alternate links of the carriersA may be provided with clamps for rigidly securing wooden heel blanksthereto,but, of course, this feature of the invention 'may be variouslymodified and more or less of the links*- be provided with clamps. yInany event, however, it is desirable that the clamps may be automaticallyactuated to clamp the wooden heel blanks as they are presented to themachine,and to automatically unclamp or discharge the finished heels. Tothis end, the trackway 61, herexinbefore described, is provided with aninclined end portion 68, Figs. 1 and 4, along which the rolls 6()carried by the clamping member 57 act as the carrier moves the clampstowards the cuttingstations.- As hereinbefore stated, the springactuated plunger 64 normally tends to separate the clamps 53, 57 and,consequently, a. heel blank may be presented between the .clamps 53 and57 prior to the engagement of the roll 60 of a clamp with the incline 68of the trackway 61, and, as the roll thereafter moves upward' along theincline 68,. the blank a, Fig. 4, will be automatically clamped andrigidly held in position for the action of the cutters. After the heelhas been finished by the operations to be hereinafter described, theheel clamps successively pass from, the end of the trackway 61, therebypermitting the spring actuated plunger 64 to separate the clamp members53, 57 and automatically discharge the finished heels.

When the blanks are placed between the clamp members 53. 57 they areheld in an inclined position relative to the vertical, as indicated in Fig. 4, and in this position are rigidly supported by the carrier as theblanks are moved past the cutting station. Idlereinafterl the 4termheightwise will be employed to designate the dimension of the heelbla-nk vertically between the clamping members 53, 57, it beingunderstood, of course, that the true heightwis'e dimension of a heel isthe distance between the tread and heel seat surfaces on a lineperpendicular to each.` The above term, however, will be employed in thebroader sense, as hereinbefore noted, and constitutes a convenientdesignationtof position or dimension with intacto respect to which thecuttersl are movable as will hereinafter more fully appear.

The heel blanks, whenl taken by the clamps, are subject to considerable.clamplng pressure which' might, in some instances, tend to liftthecarrier or link` towhich the clamp is connected. The present invention,therefore, contemplates that the carrier A may Vbeplrevented 'fromresponding to this actlon of the clamp by .confining the carrier to itspredetermined path of movement. lin thev present instance the links ofthe carrier are rovided with outer dove-,tailed portions 69, 91g. 7,whlch underlie overhangmg vportions which may be formed as gibs orguideways on the machine frame. rlhe construction described affords aconvenient means for maintaining' the carrier in its predetermined pathlof travel as the clamp; members automatically act to secure a clamp tothe carrier and 'hold it as it is moved past the cutting stations, butobviously this teature maybe variously contrived.v v

The number of molded cutters employed may be varied to' suit varyingconditions, but in the present instance of the invention two rotarymolded cutters are shown, each of Similar construction and mounted foracting, one at each side of the path of movement of the blanks orcarrier, to successively treat opposite side and rear portions of theyblanks.

Since the character, construction, mounting,

and mode of operation of each of the cutters is the same, a descriptionof one will be suiiioient.

rThe machine frame has its top portion provided with guideways? 1, Figs.3 and 7, in which is adj ustably mounted' the upright 72 carryinglaterally extendin which is pivotally mounted at a the swinging arm 75,on which one of the molded cutters is mounted, as will hereinafter morefully appear.

In order that the upright 72 may be adj usted to position the cutter forproper relation With the blank to be cut as it is fed by the carrier,the base portion of the upright 72 is provided with a lug 76y which isengaged by a threaded adjusting bolt 77 and provided with an operatinghandle 78. rllhe adjusting bolt has a collaredl portion at each side ofa iiXed lug 79 and is, therefore, held from longitudinal movement in thelug but may rotate with respect thereto, with the result that theupright 72 may be adjusted in the guideways 71.

The cutter B is connected to the swinging arm in a manner to be-hereinater'described, but for the present it is sutlicient to note thatthe cutter B moves with the arm 75 as the latter turns about its pivotalmounting 74 and that the cutter is thus movable laterally with respectto the wooden heel blanks presented b A the carrier as indicated inFigs. 3 and 7. ivotally connected to the arms 73 into swing the arm 75laterally inward toward Vthe path of movement of the y heel blanksmounted ,on the carrier. To adord proper swinging movement of the rod 81as the arm 75 swings about its pivot 7 4, the sleeve 82 is connected tothe bracket 83 by means of an arml 86, Figs. 3 and 7, having a slot 87which is engaged by pins 88 extending from the sleeve 82, theconstruction being such as to permit the sleeve 82 to rock as requiredby the changing vposition of the rod 81. rlhe 'end 89 of the rod 81 maybe provided with screw threads and suitable adj ustin sleeves 90 may bethreaded thereto to limit't e movement ofthe rod 81 through the sleeverespon-v sive-to the spring 85.

y As the wooden heel blanks traverse relatively to the cutter B, thepresent invention contemplates that the cutter shall act along the sideof the blankcommencing at thev I' breast corner towardsv the rear of theheel blank, and then move inwardly to or slightly beyond the median rearline oi the heel. As

the next blank in a series approaches the cutter, it is necessary thatthe latter should be restored to its outer or initial/position in orderto again commence its above described operation along the heel blank. Abracket 91, Figs. 7 and 8, -iS secured to the arm 75 by a bolt or otherfastening means 92, Fig. 8, and is adjustable laterally ofthe arm 75 bymeans of the adjusting screw 93, the construction being such that byloosening the securing means 92, the bracket 91, Fig. 8, may belaterally adjusted and then clamped Yin adjusted position. rllhe bracket91 projects laterally at 94 and to such lateral projection of thebracket there is adjustably secured an arm l95, carrying a stud orroller 96 which, in connection with means to be described, serves todetermine the lateral position of the cutter B. The arm may be securedadjustably .to the bracket 91 by Y suitable means such as ythe adjustingscrew 97, Fig. 7, threaded to a lug 98 on the projection 9a oi thebracket and mounted to turn in, but restrained from longitudinalmovement with respect to, a lug 99 carried by the bracket 95, theconstruction being such that by manipulation of the adjusting screw 97the position of the roller 96 maybe changed relative to the cutter B.

A templet 109 is mounted on the carrier adjacent each ot the heel blankclamps as indicated in Fig. 7, and along the templet the roll 96 travelsas the carrier moves the templet and adjacent heel blank in its path oftravel'past the cutter. rThe trailing portion of the temnlet 100 iscurved, as indicated pulse of the spring 85 as the blank'moves switches'are of fthe. samel construction ltion being such that as the roller 96travels relatively to the cutter, the effect being to causethe cutter toact along the side of the blank from the breast corner towards the rearandthen to move inwardly to or beyond the median line at the back of theblank.

` To move the cutter outwardly again after completing its operation upona blank,H

means are provided to act upon the roller 96 to move the arm 7 5v andthe connected cutter intoits outward or initial position. In the presentinstance of the invention such means comprise members 101, which, 'forVidentification, vmayv be herein Areferred to as switches, onebeinglocated adjacent'. each of the clamps on the carrler. Slnce thesethroughout and act in thel same manner in the performance of theirfunctions,- aV description of one will be ysuilicient. switch 101 Fig. 7.is pivotally mountedat 102 upon the' carrier andhas Ja biurcated.

trailing end portion embracing the. arm 52 of the clamp lto therebylimit swinging movement about' its pivot. The switch v101 has a of thenext preceding templet, theconstruci along the templet to its trailingend lportion acting upon the roller 96 as the carrier travand movesinwardly to carry the cutter about the rear of the blank, it engages theend por-v tion 103 of the succeeding switch which thereby acts as a stopto limit the lateral inward movement of the cutter, and thereafter theinclined edge portion of tlie switch,

erses the blank relative to the cutter, causes the roller 96 to be movedlaterally outward and, perforce, to similiarl move the `cutter intoitsinitial outward position to commence its next cut upon the followingblank at the breast corner'thereof as the vtemplet again takes charge ofthe lateral movement of the cutter.

As indicated in Fig. 11, it is desirable that the lateral movement ofthe cutter about the rear of the blank shall be suflicient to reach orpassslightly beyond the rear median line of the heel blank in order toinsure the complete inish of the rear portion or' the heel as thesuccessive cutters act along and about the heel. A I Heretoforereference has been made to the variation in the speed of travel ofthecarrier during the action of the cutters uponl the heel blank, andsuitable means to this end has also been described. This variation 1nspeed, and the action of the cutter upon the heel as it travels alongthe side and about the rear thereof, is graphically represented 1n Fig.11 wherein the relative traverse of the cutter and heel, as the cutteracts `along The tween the points c, d, and relatively slow between thepoints d and e as the cutter movesp about the rear of the heel crosswiseof the grain.' In other words, in a unit of-time the cutter will movealong the side'b of the heel a distance c, d, whereas, while cuttingaround the rear portion ofthe Aheel crosswise of the grain, thecutter'will move in the same unit ottime the distance ,d, therebyinsuring proper surface inishto both the side and rear portions of theheel. f

- In 'Fig'. 11 the axis 104 kaboutvwhch the vroller 96'andfthe cutter Brotate, are indicated asin alignment and such relation of the axes oftheroller 96 and the cutter is desirable in some forms of heels. By theadjustment of the roller 96 to carr the axis thereof into differentrelations wit the axls 4of the cutter, 'the same machine is adapted toproduce heels wider at the breast-'and leading end portion 103 whlchextends forwardly adjacent the rounded end portion more flat at the rearportion as theroller 96 travels along the templet 100.

In Fig. 13 the axis of the roller 96 is indicated. as having beenadjusted forward of the axis of the cutter B so that as the roller 96-travels along the templet 100 in the manner hereinbefore described, thebreast width of the heel mayl remain thel same as when the'axis of the4roller 96 and thecutter B are in alignment, but as the cutter movesabout the rear portion of the vheel a greater fullness yor rear duced.

the cutter B shall notonly have the characteristicv lateral movementhereinbefore descrlbed, butthat it may be tilted and moved -verticallyas it passes along vand about the heel and one convenient form of meansto 'these ends will now be described.

' Mounted for sliding movement in the arm 75 is the cutter pivotcarrying frame 105 provided with an upwardly extending arm 106 carryinga roller 107 adapted to move in -a trackway 108 as the arm 75 islaterally` form of pivotal connection consists of a pin 111 onl theframe 105 which engages an.

opening 112 at the lower part of the swingextension of the heel'is pro-f105` The present, invention contemplates that a iaiaeio .with the pivotas a center, and bolts 115v serve to guide the swinging :trame 110 as itmoves about its pivotal axis.

rFhe cutter B is mounted on a'shaft 116,-

Fig. 8, held in suitable bearings 117 carried by a frame 118. The shaft116 of the cutter passes through a motor 119 which may be secured to theframe 118 by suitable means, such as the bolts 120. rl`he motor 119 maybe of the usual electric type serving to impart to the cutter shaft andcutter, rotary motion. The frame 118 is adjustably mounted on theswinging trame 110 by means of securing bolts 121, and may be adjustedverticallywith respect thereto by means of an adjusting device which, inthe present instance of the invention, comprises an adjusting screw 122,Fig.l8, mounted for rotary movement in an arm 123 and threaded intoprojections from the upper bearing 117 of the frame 118, theconstruction being such that by loosening the bolts 121, andmanipulation of the adjusting screw 122, the cutter carrying frame 118may be adjusted to move the cutter upward, or downward relative to itspivotal axis. From the construction described, it will be apparent thatthe axis about which the cutter Bv tilts, passes transversely of thecutter and that the cutter may 'be vertically adjusted by hand to placethe axis in different vertical relation thereto.

rlhe means for automatically tilting the cutter about its axis as itoperates upon a heel blank, may be variously contrived, but in thepresent instance of the invention comprises an arm 124, Fig. 7,pivotally mounted l the clamp screws 129, Fig. 7.

rllhe arm 124 has secured thereto the upwardly extending arm 130, Fig.7, connected at its upper end portion to a link 131 jointed tothe-swinging frame 110 at 132,v the construction being such that as theroller 126 is moved by the passing cams or patterns 127 on the carrier,the swinging' trame 110, and, perforce, the cutter and motor carriedthereby, will be moved about the pivotal axis 111. The roller 126 may bemaintained in operative relation with its cams or patterns 127 bysuitable means which, in the present instance of the invention, consistsot a spring 133, Fig. 7, encircling a rod 134 which passes through aswivel block 135 mounted on one of the arms 73, the other end of the rod134 being pivotally connected to the arm 130 at- 136, the constructionbeing such that the spring 133 normally tendsto depress l,the roller 126into contact with its cooperating cams or patterns 127. rl`he link 131may be made adjustable in length byl means .of a reverses crewturn-buckle 137.

'llhejtrackway 108 in which the4 roller 107 travels, ismounted upon aslide 138, Figs. 1 and 7, guided bysuitable dove-tailed bearings 139formed in' the uprights 140 risingfrom the mac'hine frame.

The' slide 138 is connected to a lower slide 141 by an adjusting screwl142 which may be appropriately turned by vhand .for relaf tivelyadjustingthe slides 138 and 141 by means of a handleor crank arm 143.

rlhe slide 141, which, as describedkis vertically'movable in the frame.140, is provided at its lower end with a roller 144, Figs. 1 and 7,which rides upon cams or patterns 145 mounted on the carrierA, theconstruction being such that as the carrier is moved to feed the blanksto the cutters, the roller 144 will` ride upon the cams or patterns 145and raise or lower the cutter through the connections described to varyits position heightwise of the blank being treated.

inasmuch as the carrier A is formed of link members flexibly connectedtogether, and carries the cams or pattern devices for controlling thetilting and vertical movement of the cutter, the cam or pattern devices127, 145, are formed in sections corresponding to the link members whichcarry them and are preferably connected thereto detachably by means ofcap plates 146, Fig. 7, the construction being such that the cams orpatterns maybe readily removed and replaced by others to change thetilting and vertical movements of the cutters as pre- .superposed viewstaken at right angles.

The full line figure is taken with the line vof sight parallel to thedirection of feed;

the dotted line gure is taken with the line orIl sight perpendicular tothe direction of feed. ln the dotted figure the point f is theprojection ci the axis of tilt through the angle it, z'. (This is theaxis 111); and in the full line figure the point f is a point of thataxis which would extend across the paper parallel to the word ln'ventor,if it were drawn in. Assuming that the axis about whichv the cuttertilts is at f, Fig. 6,

arrows at h and the heightwise or lifting movement of the cutter isindicated by the arrows vl, Fig. 6, the effect being, in the presentassumed instance, to produce a fulll ness at the rear portion of theheel leading scribed as a to the heel seat, as indicatedby dotted linesat g, Fig. 6.

By shifting the axis of tilt relative -to the cutter, the variation inheel shapes produced by the action of the cutters on the heel blank,4may be indefinitely varied. Likewise, either by changeof cams orpatterns, or by adjustment of the roller 126, for effecting the tiltingaction of the' cutter, its degree andtime of tilting action may beindefinitely varied and the machine hereinv deood practical form of thepresent inventlon, be adapted for the formation of wooden heels ofgreatly varying styles and shapes.

It will be noticed that the cutter head is I shown as of considerablygreater vertical depth than the heel. This enables different portions ofthe cutter 'to be used at different' parts of the heel periphery andpermits the. cutter, therefore, by virtue of the vertical shift, tocombine different curves required in the peripheral surface at thebreast and at the 4rear of the heel.
